Uttar Pradesh, Maharashtra, and Gujarat contributed 45% of India’s residential solar rooftop additions in September 2026. While the PM Surya Ghar: Muft Bijli Yojana has reached a total capacity of 17,561 MW, monthly installation speeds have slowed for the third straight month. Investors are keeping a close watch on whether logistical bottlenecks in converting applications to installations can be resolved to maintain the program's momentum.
Uttar Pradesh, Maharashtra, and Gujarat have emerged as the primary engines of India’s residential rooftop solar expansion. Under the PM Surya Ghar: Muft Bijli Yojana, these three states together accounted for nearly 45% of the total capacity added in September 2026. Uttar Pradesh led the country with 234.46 MW in new installations, followed closely by Maharashtra and Gujarat, which added 208.04 MW and 165.6 MW, respectively. By the end of September, the program’s cumulative installed capacity reached 17,561 MW.
The Role of Subsidies in Growth
The strong performance in these states is largely driven by the 'Affordability Effect.' Government data and industry reports indicate that the federal subsidy provided under the Muft Bijli Yojana is acting as a critical bridge. In many regions where electricity tariffs are low, the financial benefit of installing rooftop solar would typically be too slow to justify the cost. The subsidy removes this barrier, making solar energy a viable option for a much larger number of households. Roughly 60% of current installations under this scheme are located in areas that would likely not have seen significant solar adoption without this financial support.
Signs of Slowing Momentum
Despite the impressive total capacity numbers, the speed of adoption is showing signs of cooling. National monthly capacity additions have declined for three consecutive months. The monthly addition fell to 1,357.52 MW in September, down from 1,592 MW in July. While consumer interest remains high—with over 600,000 applications processed in September alone—the challenge lies in moving from registration to a commissioned, operational solar system.
Investor and Sector Perspective
For investors monitoring the solar value chain, including equipment manufacturers and installation firms, the primary concern is the conversion rate of these applications into actual projects. Logistical hurdles, such as delays in grid connectivity and the approval process, are currently acting as a bottleneck.
Furthermore, the sector faces structural risks. While the domestic solar manufacturing industry is expanding, companies remain exposed to supply chain risks, particularly the reliance on imported raw materials for panels and cells. Additionally, stiff competition in government-backed tenders continues to place pressure on profit margins for equipment makers. As the program transitions from serving early adopters to the broader mass market, maintaining the growth rates seen in previous years will depend heavily on the government’s ability to streamline approval processes and maintain subsidy flows. Moving forward, stakeholders will be tracking monthly commissioning data and policy stability as key indicators for the health of the residential solar ecosystem.
